i-MapNJ Geology is an interactive mapping application that provides information about
New Jersey's Geology, Aquifers, Wellhead Protection Areas, Earthquake Epicenters, Abandoned Mines and more.
Sep 2011: Updated the Public Community Water Supply Wells layer and Well Head Protection Areas (Community) layer.
- The geology of New Jersey is uniquely diverse and interesting.
There are four physiographic provinces (Valley and Ridge, Highlands,
Piedmont, Coastal Plain) each with distinctive rocks and landforms.
In addition, Glacial deposits mostly of Late Wisconsinan age (about
20,000 years old) cover the surface in the northern-most part of the state.
- Ground water is the primary drinking and agricultural water source for
the residents of New Jersey. Ground water is contained in porous rocks and
sediments called aquifers. They are recharged by rainwater and interact with
other surface water bodies such as lakes and streams. In New Jersey, ground
water resources are evaluated and the distribution of the aquifers wellhead
protection areas are mapped.
- New Jersey has experienced many small earthquakes in the past decade.
The State Police and NJGS work together to identify high earthquake hazard
areas and plan emergency response under a Federal Emergency Management
Agency (FEMA) grant.
- New Jersey has a long history of mining for iron, copper and other minerals.
Abandoned mining operations pose surface stability problems that must be addressed.
